EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 466,889, dated January12, 1892.

' Application filed July 2, 1891. Serial No. 398.243. (N0 model.)

To all whom it may concern:

Be it known that we, EMILE CORNELY and ROBERT CORNELY, residents ofParis, in the Republic of France, have invented new and usefulImprovements in Embroidery-Machines, which are fully set forth in thefollowing specification.

The invention will be described in connection with the accompanyingdrawings, in which- Figure I is a side elevation of the improvedmachine, partly in vertical section. Fig. II is a vertical sectionthrough the nipple-tube. Fig. III is an elevation, partly in Verticalsection. Fig. IV is a vertical section showing the looper mechanism andconnected parts. Figs. V and VI are details in plan and vertical sectionshowing the looper mechanism, and Fig. VII is a view of the newembroidering-seam.

The present invention consists in the construction of the looper whichlays its thread into the needle-hook and by means of which the machinecan work either with one or with two needles, which latter can beemployed at various distances one from the other. To obtain this resultwe employ a looper which works on the principle of the one shown anddescribed in Letters Patent No. 392,010, of October 30, 1888, but of adifferent construction, as represented in Figs. IV, V, and VI.

The looper consists of the part P, which is provided with. a looper-tubeh, Fig. IV, when working in conjunction with a single needle B or withtwo looping-tubes, Fig. VI, when working in conjunction with two needlesB and L. The looper-tubes h '11 by their oscillating motion lay theirthreads into the needle-hooks, as described in Patent 392,010. The partP plays in a groove of the wheel 0, which can be turned by thecrank-handle M through the gearing 4, 5, 6, 7, and R. The cylindricalpart b of part P is fitted into a hole of the gear-shaft G, which holeis bored eccentrically into said gear-shaft, and by the oscillatingmotion of said gear-shaft the looper-tube it or the looper tubes h '1;execute their proper movements for laying their threads respectivelyinto the needlehooks B or B and L, the part P being guided also by thefriction-stud c, which plays in the slot (1 of wheel 0, Fig. IV. .Thelooper-tubes 7L 1',

Fig. VI, can be employed at various distances one from the other toproduce larger or smaller work, and for each case the distance of theholes in the nipple and in the stitching-plate must correspond withthose of the loopertubes. The part P is held in its place by the actionof a semicircular bolt m, which can slide on the two studs 2 and 3, Fig.V. By turning the bolt m so that it will clear the part I" the lattercan be withdrawn easily when it is tobe replaced by one of another kind,and by these means the machine can work with one or with two needles,and thus produce a great variety of work.

For working with two needles two threadspools are required. Theyare seton the double spool-holder composed of the boss S and arms T U, whichcan be turned from the crank-handle M by means of the gearings 4 5 6 7 RO 8 9 10 11, Fig. I. The thread from bobbin K is passed into therevolving thread-carrier O, as described in our Letters Patent 405,147,dated June 11, 1889. For regulating its tension a thread-guide 70, Fig.I, is employed. It is provided with several holes, through which thethread is passed to obtain the desired tension, o'ra tension V, Fig. II,may be employed,whose spring it acts as a take-up for the thread whensuch should be needed. Both devices are secured to the hub of the wheelW, to which the revolvingthread-carrier G is also secured, and which isoperated from the main shaft Y by the action of the pinions 47 and 48and by an intermediate series of pinions, represented at Fig. I andshown and described in former patents. By loosening the pinion 47 it canbe shifted out of gear from pinion 4:8, and the revolving motion of thethread-carrier G will thereby be stopped, and the machine will then onlyproduce the simple chain-stitch; but although the said thread-carrier 0may be un coupled from the main shaft it still remains connected withthe crank-handle M and can be turned by it, and this modification in themachine can be employed to produce a new ornamental seam in thefollowing manner: By employing a thick thread or chenille a on the spoolK and on the thread-carrier C, Fig. III, and a similar thread orchenille 13 which passes through the hollow needle-bar A, Fig. III, andthrough the nipple Z, and by then turning the crank-handle M rapidlyduring ICO the Work the needle-hook will produce small circles ofchain-stitch embroidery (1 Fig. VII, and the thread-carrier 0 will atthe same time be" turned so as to Wind its thread a once around thethread 11 at each turn of the crank-handlevM, and will thus produce theembroidery represented in Fig. VII, the two threads a and 12 beingfastened to the ma terial by means of the chain-stitch circles d Theeffect of this embroidery can be varied according to the colors used andto the tension employed on the threads.

\Ve claim-- 1. In an embroidering-machine, the combination, with theneedle or needles and with operating mechanism therefor, of anoscillatory looper-support having an eccentric recess, a looper providedwith athread tube or tubes and having a boss which fits in said recess,said looper being removable from its support, and a holding plate orbolt for securing said looper in position while in operation,substantially as described.

2. In an embroidering-machine having a universal feed, the combinationof a gear- Wh eel connected with the crank-handle of the feed mechanism,an oscillatory looper-support inclosed by the hub of said wheel andhaving an eccentric recess, a removable looper comprising a cylindricalpart which fits said recess and a lateral extension which slides in agroove in the face of said Wheel, and a bolt for holding the looper inposition while in operation, substantially as described.

In testimony whereof we have signed this specification in the presenceof two subscribing Witnesses.
